关于red hat9共享ADSL

ananasky

各位兄弟，我刚用linux，请问怎么用red hat9作代理共享ADSL啊，双网卡的，我在网上找了几篇资料，可都看不懂，原来我的liunx可以用ADSL拨号上网，按资料改了以后拨号都拨不上去了。请朋友们帮看看，谢谢


9.配置DHCPD使内部网络机器自动获得IP地址.

修改/etc/dhcpd.conf, 修改后如下:

#Start of /etc/dhcpd.conf

ddns-update-style interim;

ignore client-updates;

subnet 192.168.0.0 netmask 255.255.255.0 {

# --- default gateway

option routers 192.168.0.1;

option subnet-mask 255.255.255.0;

option nis-domain "domain.org";

option domain-name "domain.org";

# --- option domain-name-servers ISP's DNS1,ISP's DNS2;

option domain-name-servers 192.168.0.1,142.177.1.2,142.177.129.11;

option time-offset -18000; # Eastern Standard Time

# --- Selects point-to-point node (default is hybrid). Don't change this unless

# -- you understand Netbios very well

# option netbios-node-type 2;

range dynamic-bootp 192.168.0.2 192.168.0.254;

default-lease-time 21600;

max-lease-time 43200;

}

#End of /etc/dhcpd.conf


0.修改/etc/sysconfig/iptables(把原有的内容都删除),修改完如下，以使VDSL和代理在开机时自动生效。

# Generated by iptables-save v1.2.6a on Tue Oct 29 22:28:14 2002

*mangle

REROUTING ACCEPT [3184]

:INPUT ACCEPT [3182]

:FORWARD ACCEPT [2]

:OUTPUT ACCEPT [2797]

OSTROUTING ACCEPT [2799]

:FORWARD ACCEPT [370]

12. 修改/etc/sysctl.conf，把net.ipv4.ip_forward设置成1，如下：

net.ipv4.ip_forward = 1

如此一来，每次你重新启动机器或重新启动网络服务(/etc/init.d/network restart)时就会自动启动ip转发功能！

13.关闭ipchain自动启动服务,开启iptables自动启动服务(如果已经设定,可以忽略这步)

输入以下命令行:

[jackey@localhost jackey]$ su

Password:

[root@localhost jackey]# cd /etc/init.d/

[root@localhost init.d]# chkconfig --del ipchains --level 2345

[root@localhost init.d]# chkconfig --add iptables --level 2345

上面的我都是直接抄的，重启机子以后网都上不去了，但ADSL可以拨号，不知道什么原因，拜托朋友们帮忙看看，还有能不能有份关于这个的详细教程，让我这样的菜鸟能看懂的，多谢了

呵呵，我搞定了，原来不用那么复杂的

REDHAT9可以用一张网卡来做路由主机么 ?
